After installation, its web interface can be accessed using the browser or Mobile & Desktop Apps on Windows, Linux, and Mac, iOS, and Android.

    Under the name Omnibus, Mattermost released package, a complete stack of the free messaging system, can be installed with just a few commands. In addition to Mattermost itself, the administrator can set up PostgreSQL as a database, Nginx as a proxy web server, and Certbot to issue and renew SSL certificates in no time at all.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
